摘要

给出了改进二元决策图排序计算的启发式算法。第一步,基于网络的拓扑结构,生成一个层次变量排序。这一初步结果是由随机进化技术控制的增量操作进一步细化。介绍了bdd的一个新特性,它可以加速常用的操作。给出了实验结果。二进制决策图(bdd)作为表示开关功能结构的一种手段已经存在了很长时间,但直到最近它们才出现在数字电路设计自动化工具的实现中

Advanced ordering and manipulation techniques for binary decision diagrams
Heuristics leading to improved ordering computation for binary decision diagrams (BDDs) are given. An initial step, based on the topology of the network, generates a hierarchical variable ordering. This initial result is further refined by incremental manipulation governed by the stochastic evolution technique. A new property of BDDs is introduced as well, which accelerates commonly used operations. Experimental results are presented. Binary decision diagrams (BDDs) have been known for a long time as a means to represent the structure of switching functions, but only recently their use emerged in the implementation of design automation tools for digital circuits.<>
